DOOR-FASTENER- Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed February 3, 1904:. Serial No. 191,909.

To ail whom, it may concern:

Be it known that I, GEORGE W. NILES, a citizen of the United States,residing at Vanwert, in the county of Van Wert and State of Ohio, havemade certain new and useful Improvements in Door-Securers, of which thefollowing is a specification.

My invention is an improvement in that class of door-securers which areadapted for use independently of the ordinary latch or bolt forming anattachment of a door, the same having a member provided with a claw thatengages the door-jamb and another member which is adjustable on thefirst-named one and adapted to abut the adjacent edge of the door, andthus prevent the latter being opened from without.

The details of construction, arrangement, and operation of parts are ashereinafter described, and illustrated in the accompanying drawings, inwhich Figure 1 is a perspective view of my improved door-securer. Fig. 2is a plan view of the wedge member and the means for clamping it toother parts. Fig. 3 is a plan view of the jamb-plate. Fig. 4 is a planview of the door-abutting plate. Fig. 5 is an illustration of the mannerof applying the doorsecurer in practice.

1 indicates an elongated plate having a claw 2 at one end, a lengthwiseslot 3 adjacent to the other end, and a series of notches or open slots4 in the middle portion of its upper edge. This plate is applied to thejamb when the door-securer is put in use, as shown in Fig. 5, the claw 2entering the wood, as there shown.

5 indicates an elongated plate having a rightangular flange or shoulder6 at one end, a lengthwise slot 7, a notch 8 in its upper edge, and acatch or locking device 9, which is pivoted to said plate 5 and providedat its free end with a lateral projection or flange 10, which is adaptedto enter the notches 4: and 8 in the respective plates 1 and 5, when thedoor-securer is applied as shown in Fig. 5.

11 indicates a wedge which is arranged on the inner or claw side of thejamb-plate l and is provided with a laterally-projecting screwthreadedstud 12, to which a nut 13, having an enlarged and milled head, isapplied. The

plates 1 and 5 and catch 9 are preferably constructed of sheet-steel.The wedge 11 may also be constructed of steel or any other suit ablemetal,

The manner of applying the door-securer is as follows: The door y beingopen and the nut 13 being loosened to allow the plate 5 and wedge 11 tobe turned or swung back out of the way, the plate 1 is applied to thejamb X in horizontal position, with its claw 2 abutting the shoulder:20. The door is then closed so that it abuts the shoulder 00, as shownin Fig. 5, whereby the claw 2 is forced into the jamb to a greater orless depth. The plate 5 and wedge 11 are then swung into horizontalposition and slid forward, so that the flange 6 of plate 5 abuts thedoor, whereupon the catch 9 is dropped into engagement with the notch 8of plate 5 and one of the notches of the jamb-plate 1. The thickness ofthe door y will obviously determine the distance between the claw 2 andflange 6 of the respective plates, and accordingly the particularnotch4= which will be engaged by the catch 9. The wedge 11 is thenforced inward so that its point presses between the jamb X and thejamb-plate 1, whereupon the nut 13 is screwed up tightly, so as to clampthe three parts 1, 5, and 11 firmly together. It will be seen that bythis arrangement the door y is firmly secured, since the catch 9 willprevent the door-plate 5 from sliding on the jamb-plate 1, even ifinsufiicient friction for this purpose should be applied by the nut 13.It will be further seen that the wedge 11 crowds the outer portion ofthe jamb-plate 1 away from the jamb, and thus tends to hold the claw 2firmly engaged.

What 'I claim is- 1. The door-securer comprising the slotted jamb-platehaving a claw at one end, another slotted plate having a flange at oneend, a wedge arranged slidably on the innerside of the jamb-plate, meansfor clamping the three parts together, and a catch pivoted to thedoor-plate and adapted to engage with the two plates and lock themtogether, substantially as described.

' 2. In a door-securer of the class specified, the combination, with thejamb-plate having a claw at one end and provided with a series ofnotches in its upper edge, and a second plate having a door-abuttingflange at one end and provided With a notch in its upper edge, of acatch pivoted to the door-plate and 5 having its free end bent laterallyand adapt- GEORGE W. NILES.
